Which 70-200L

Hey just wondering which 70-200L would give the best results, when using the 1.4xII, any thoughts....

I haven't used one myself, but out of the f/4 and f/2.8 I'd go for the f/2.8, seeing as though the 1.4TC will make you lose 1 stop.
Good review HERE.

What do you mean best results? I use the 2.8L with a 1.4x TC and I get great shots.

1.4x TC will work very well on either version.
With the 2.8, you have more margin for stopping it down without losing too much light.

Perfectly put.
That's what I was trying to say I think I need more sleep

all are great. how much do you want to spend is the question?

I went for the f/4L not because it was less expensive but because it was much smaller/lighter. I use it with the 1.4X T-con quite a bit, but it's definitely not a good choice for handheld shots on an overcast day.

I'd choose the F/4L IS over the non-IS version (that I have).
